Off-road hashing (running) trail through muck, mud or other wet areas. Term derives from shigella/shigellosis - bacteria causing dysentery occurring most frequently in areas of poor sanitation such as pig sties and back-water swamp lands. Term first used by Brits & Aussies on Hash House Harrier runs (in Asia) in 1940's.
The hares laid much of the trail through deep shiggy and nearly every hasher had to wash up prior to down-downs. On On!
